On-camera flash discovery.

Doing some Macro work in my back yard yesterday I discovered that the TTL functions properly with a screw-mount lens, even when used with extension tubes at ranges in the 12"-18" area.

I thought that TTL was only useable with "digital lenses".

Well, TTL means Through The Lens, so metering is done through the lens nsd will work with any lens AF or MF.

What felix said, it's through the lens, no matter the lens.
